Assertion error : assert starts == sorted(starts)

[rnaomics]

I got the following error when I did the iCount segment step?

File "/data/groups/anko/mohamed/Install_packages/miniconda3/envs/env_nf/lib/python3.9/site-packages/iCount/genomes/segment.p y", line 465, in _process_transcript_group
assert starts == sorted(starts)
AssertionError

I was trying to find the source of the error. It seems that if the gene is in the reverse strand, this error occurs. In my case, I used the mm9 annotation files(https://hgdownload.soe.ucsc.edu/goldenPath/mm9/bigZips/genes/).
